What is DataDump™
DataDump™ DataDump ™ is a free tool which allows you to dump segments of data, or all of the data, from an original source image or physical/logical device. It can be used for the following:

7. Once the Source and Output File have been selected, click on the Extract button. The will copy all of the data from your source into a single image file.
Extracting a Subset of Data
To extract a subset of data is a simple process. Identify the start of the data and the number of blocks you wish to extract. This can be done via the Start and End LBA Spin Edit boxes, or the Track Bar to the right of each Spin Edit box.
The start and end values use Logical Block Addressing. You will need to manually adjust any absolute byte offsets to LBA for the correct start offset to be selected. You can use the following formula:
| Code Block | ||||
|---|---|---|---|---|
| ||||
LBA = byte offset / block size |
It is important to note that LBA is a whole number, so any remainder resulting from the division should be truncated or rounded down to the nearest whole number. In addition, the first LBA on a storage device is typically 0, not 1, so the LBA of the first block is always 0. Typically, with an image from a hard disk, the block size would by 512 bytes.
You can then select the End LBA or the Block Count to set the number of bytes to be extracted.
